  let form = new formidable.IncomingForm();
  form.keepExtensions = true;

  form.parse(req, (err, fields, file) => {
    if (err) {

Mongodb has a limit of 16MB on the size of document which you can save to a collection.

Since you are trying to save videos of size greater than 16mb to your freecoursevideo collection, you are getting an error.

Solution:-

You will have to Gridfs to save documents of size greater than 16mb.

I your case i would suggest you get rid of freecoursevideo collection and save all your videos in gridfs whether it is more than 16mb or not. So that you don't have to query two places for getting your videos.

So how to save to gridfs?

  • To start with just try to put some videos using mongoshell. Just navigate to the bin folder of your mongo database tools.

Ensure that the bin folder has following content.

enter image description here

  • Open command prompt at this location. Run the below command by replacing , , <DB_NAME> and <PATH_TO_VIDEO>

    mongofiles --host=<HOST> --port=<PORT> -d=<DB_NAME> put <PATH_TO_VIDEO>

  • Above command will save the video in fs.files and fs.chunks collections. Name of these collections are predefined by mongo and cannot be changed.

  • Above exercise will you the understanding of how gridfs works. Then you can go ahead look for mongoose way of doing this. Adding a link to article that may help.
